Nick Gordon was busted Saturday for kidnapping and beating his girlfriend, according to reports — less than a year after he was found legally responsible for the 2015 death of former squeeze Bobbi Kristina Brown.

Cops collared Gordon, 28, after his girlfriend of two months, 26-year-old Laura Leal, accused him of punching and hitting her and refusing to let her leave his home in Sanford, Florida, the Daily Mail reports.

The pair started fighting Friday night after watching the NBA finals at a nearby bar, where Gordon thought Leal was trying to “hook up” with one of his pals, according to the police report.

She insisted there was nothing going on, but he didn’t believe her, and kept saying he just wanted her to tell the truth, and “would not get mad” if she confessed, the report states.

Gordon eventually gave her the option of leaving, but when she tried to walk out, he allegedly flew into a rage, punching her and refusing to let her go.

Leal claims Gordon had already smashed her cellphone a few weeks ago, so she tried to contact her sister for help via Facebook — and Gordon allegedly took her laptop away and hid his own phone, the report says.

He allegedly continued to beat her through the night, and then just after dawn, she finally woke up Gordon’s mom, who saw the injuries and drove Leal to her sister’s house, where she called the cops, the Mail reports.

When the officers saw her wounds, they sent her to the emergency room.
